  • Function
Sirius Comfort has a built-in VAV regulator for needs-driven control of airfl ows. The damper solution will choke the pressure at high fl ow rates and will maintain a low sound level. This may reduce the need for additional dampers and sound attenuators in a duct system.The unit is equipped with a heating coil for waterborne heating of intake air. Sirius Comfort is delivered with Belimo MP Bus, LON, Modbus or Belimo KNX for direct bus communications with building automation systems. 

Measurement deviation for the area:

10 - 20% of nominal: ±25%
20 - 40% of nominal: <±10%
40 - 100% of nominal: <±4%

At T-pipe situation, a distance of at least 5 x ØD is recommended in order to maintain same measurement precision.


The diffuser front can be supplied with integrated motion sensor. Product sheet for motion sensor can be found on our website: www.trox.no
